R1100S

>I wouldn't be surprised for the S to vibrate more. The S was a regular Boxer
in a higher state of tune. Compression ratio was higher than a regular
boxer. Don't know about possibly higher performnace cams and/or larger valve
sizes. Can't remember now since it was first introduced. But I do remember
at introduction that the extra power came from normal  hot rodding
techniques.

I rode an R1100 S for 3 days of an Edelweiss trip in the French Alps.   The
next 3 days I got a brand new hex-head 1200GS.   I liked the GS lots more and
was quicker on it in the hills due to the better riding position, better
brakes and more grunt, but I didn't feel the S was very vibey.   It wasn't as
smooth as the GS, but I attributed that difference to balance shafts.  The S
seemed on par with my 1150 RT as far as vibration.   Very livable.   I just
fail to see what that riding position offers anyone on real roads.   I don't
even like being bent over like that on a track because it shortens my sight
lines through the corners.

>I'd expect that if you took compression back down to regular Boxer level ie
R1100 RT etc, that vibration would decrease somewhat.

Easily fixed, Bruno, just leave the break in oil in for 10,000 miles or so.
Compression will go down!!!
